Storage container, manufacturing method of storage container, and reusing method of storage container

Abstract

A storage container includes a main body including a storage portion having a space for containing a liquid cartridge and a peripheral edge portion forming an opening for containing the liquid cartridge in the storage portion, and a lid member covering the opening. The peripheral edge portion includes a surface facing the lid member, a welded portion on the surface and is welded to the lid member, and a structure having a first layer bonded to the surface and a second layer stacked on the first layer.

 a surface facing the lid member, 
 a welded portion on the surface and welded to the lid member, and 
 a structure having a first layer bonded to the surface and a second layer stacked on the first layer. 
   
     
     
         2 . The storage container according to  claim 1 , wherein the welded portion is continuously formed along a circumferential direction of the opening. 
     
     
         3 . The storage container according to  claim 1 , wherein the welded portion has a projection shape. 
     
     
         4 . The storage container according to  claim 1 , wherein the welded portion is arranged closer to the opening than the structure when viewed from a direction perpendicular to the surface. 
     
     
         5 . The storage container according to  claim 1 , wherein the lid member covering the opening is welded to the welded portion. 
     
     
         6 . The storage container according to  claim 1 , wherein the second layer is a release layer. 
     
     
         7 . The storage container according to  claim 6 , wherein the structure includes a third layer between the first layer and the second layer. 
     
     
         8 . The storage container according to  claim 7 , wherein at least one of the first layer, the second layer, or the third layer is colored. 
     
     
         9 . The storage container according to  claim 1 , wherein the liquid cartridge includes a liquid ejection head configured to eject ink. 
     
     
         10 . The storage container according to  claim 1 , wherein a plurality of the structures is stacked on the surface of the peripheral edge portion. 
     
     
         11 . A manufacturing method of a storage container including an opening, a main body having an peripheral edge portion forming the opening, and a lid member covering the opening, the manufacturing method comprising:
 preparing the main body and the lid member including a structure having a bonded layer;   welding the lid member to the peripheral edge portion; and   transferring the structure from the lid member to the peripheral edge portion.   
     
     
         12 . The manufacturing method of a storage container according to  claim 11 , wherein the peripheral edge portion and the lid member are welded to each other via a welded portion. 
     
     
         13 . The manufacturing method of a storage container according to  claim 12 , wherein the structure is transferred from the lid member to the peripheral edge portion in such a way as to satisfy R-(H-h)>L, where a height of the welded portion is R, a height of the structure is H, and a height of the bonded layer is h, in a direction perpendicular to a surface of the peripheral edge portion facing the lid member, and where a distance between the welded portion and the structure is L, in a direction parallel to the surface. 
     
     
         14 . The manufacturing method of a storage container according to  claim 11 , wherein the transferring includes transferring the structure from the lid member to the peripheral edge portion, the structure including the bonded layer that is bonded to a surface of the peripheral edge portion and a release layer that is in contact with the lid member before the transferring. 
     
     
         15 . The manufacturing method of a storage container according to  claim 14 , wherein the structure having a fixing layer between the bonded layer and the release layer is transferred from the lid member to the peripheral edge portion. 
     
     
         16 . The manufacturing method of a storage container according to  claim 11 , wherein the welding and the transferring are performed at the same time. 
     
     
         17 . The manufacturing method of a storage container according to  claim 11 , further comprising determining a number of times the main body is reused, from a state of the structure on a surface of the peripheral edge portion facing the lid member. 
     
     
         18 . The manufacturing method of a storage container according to  claim 11 , wherein the lid member is welded to the main body in which a liquid ejection head configured to eject liquid is contained. 
     
     
         19 . A reusing method of a storage container for containing a liquid cartridge, the storage container including a main body that includes a storage portion having a space for containing the liquid cartridge and an peripheral edge portion forming an opening for containing the liquid cartridge in the storage portion, and a lid member covering the opening, the peripheral edge portion including, on a surface facing the lid member, a welded portion that is welded to the lid member and a structure having a first layer bonded to the surface and a second layer stacked on the first layer, the reusing method comprising:
 collecting the main body from which the lid member is peeled off; and   determining a number of times the main body is reused, from a state of the structure.   
     
     
         20 . The reusing method of a storage container according to  claim 19 , wherein the collecting includes collecting the main body in a state where a liquid ejection head configured to eject liquid is contained as the liquid cartridge.
